Retail operations are finding biometric point-of-sale systems that are used for both tracking employee actions as well as for time and attendance are a great tool in fighting inventory shrink and labor fraud, according to a Point of Sale News article.

Among the regular employee actions that such systems are able to stop include buddy punching, which is when an employee will clock-in or out another employee who is not at work at the time.

In addition to requiring employees to unquestionably be present to get paid, such systems are also being used to tie employees to each transaction they perform through having them login to the system they are using through biometric modes such as their fingerprint.

While the systems increase accountability of employees by tying them to their actions, the systems also increase accountability of manager actions by removing the possibility of lost, stolen or shared override codes or cards that enable voids on the system, instead requiring managers to perform each transaction override personally.
